In the count for the House of Representatives, the AEC still classed six seats as close, with a one per cent difference between leading candidates.

Closest is Barton in NSW where there's just 14 votes between Liberal Nick Varvaris and Labor's Steve McMahon.

Much attention has centred on the Victoria seat of Indi, where Liberal Sophie Mirabella is facing a strong challenge from independent Cathy McGowan, 764 ahead at close of counting last night.

Mr Diak said the AEC will consider some 2000 postal votes on Wednesday, as it did on Tuesday, when Ms Mirabella gained some 15 votes in every 100 counted. There could be as many as 10,000 postal votes altogether.

"There are lots of people praying and crossing their fingers and toes," she said.
